Hello community. Sooooo looking for somebody anybody who knows how I could get my posiden z illuminated mechanical keyboard to enter into legacy support or bios mode or whatever it is so that the keyboard will configure with my ps4. Not sure if i need to press certain keys or get software to do so. The keys light up and the ps4 detects the keyboard when I plug it in but nothing will type or work in my games or in the ps4 menu!!! Really want this to work thank you for your time regardless
